Mig-21 Continuous Cockpit Shaking and Shuddering

[migMan3]

After the latest patch from ED last night, (assuming it was pushed to the Steam client as well...) I'm seeing bugs.

 

Preconditions:

1) The user is performing a ramp start and takeoff

2) During the take-off run, the plane shudders and shakes as it bounces along the runway (expected).

 

Postconditions:

3) After taking off, the cockpit view continues to shake and shudder with the same effect as the runway. Gear is raised, flaps are up, and yet, the cockpit view vibrates/shudders every 3-5 seconds after I take off and this continues for the duration of my time in the air.

 

Interim Fix for Users:

1) If the user has the Mig-21bis "special" settings for cockpit shake and shudder set to the standard value of 100, this seems to cause the bug--and it shouldn't. A value of "100" is listed as the simulation setting in the manual.

For the time being, however, if you don't want to deal with infuriating, seemingly scripted cockpit shaking after takeoff, set the value to "0." Unfortunately, this means you get no more dynamic shaking and shuddering when you should, but it gets rid of the extra madness.

 

Notes:

I am using the Steam version with Mig-21bis and Mig-15bis modules installed.

 

I am running on 64bit Win 8.1.

Exactly similar, of the blow during flight in formation with colleagues, that made me lose considerably some energy, and impossible to make of the formation.

I also find the different autopilot at the level of the movements.

I also use the steam version and Windows 8.1 64Bit (Huey, Mi-8, FC3, A-10C, CA, Black shark 2, P-51 and BF109 Installed)

 

Sorry for my bad English ...

No worries friend! Your English is better than my French :smilewink:

 

I think I understand what you're saying. Personally, I could not verify if the cockpit shaking/shuddering was actually an impact of the flight model, or with the "special" cockpit shaking settings. All I know is that reducing the cockpit shake value to 0 instead of 100 will fix the problem...

[Cobra847]

We're investigating this issue.

[cro_mig_21]

I noticed the shaking effect also happening in level flight but those shakes are so subtle and apart (at least on my example and I left the default 100% cockpit shake level) that I thought that was a new feature and even got to appreciate the new effect as I imagined a real MiG would behave...but then again...I dont know if it is the deal..maybe some real world pilot input?

[Art-J]

I also thought it was some new, undocumented feature :D (even though it didn't make much sense). In my case, the shuddering is very subtle and not frequent as well.

 

The most bizarre thing is... Today, when I loaded the startup tutorial mission to test my CPU overclock results with some choppers nearby and decided to taxi, takeoff and do some flying around, the shaking was not there at all (?!).

 

However, as soon as I created my own mission later (with cold start), it was back again.

Bugs are just undocumented features, after all :smilewink:

 

You are correct, I believe. The shuddering is periodic, but it seems to vary for me. One mission it will be very violent and frequent. The next mission, it is mild and farther apart. One thing is for sure, within a single mission session, once you get up, the cadence of the shaking seems to remain consistent. Perhaps it has something to do with the angle of attack at takeoff/speed? I will experiment more tonight when I am done with my actual job of doing QA :joystick:

[migMan3]

Ok, so I've had a chance to investigate more. I am so tempted to say that this is a feature, but its also new--and to be honest, distracting/annoying. I'm hoping it is just a bug.

 

Flight 1:

- Normal takeoff config

- High speed/low angle of attack

- Noticed violent vibrations with gear; lessened with speed and after the gears were up. Hmm...

 

Flight 2:

- Normal takeoff config

- Low speed/yanked a higher angle of attack

- Again, violent vibrations with gear; lessened with speed and after the gears were up.

 

Angle of attack does not seem to have a significant impact on the initial vibrations. Gear, however, does.

 

As I said above, this feels like it could be a feature, but the effect itself feels exaggerated. It may be an attempt at realism, or a defect in the head shaking component of the module. Again, setting cockpit shake in the Mig-21bis settings to 0 seems to lock things down. Unfortunately, it is the rapid nature of the vibrations that are so distracting--even if accurate, the screen is vibrating without my actual head--so I feel very detached.

[cro_mig_21]

Actually the cockpit is vibrating rather than the head..if you look outside you can see canopy shake but not the view outside itself..it stays calm.

[Akatsuki]

Same issue for me.

[ThePanic]

I'm also experiencing this same issue.

[Rider1]

same here. That shuddering did not occur before the last update

[DaHunn]

any update on the shaking?

i also see this shaking behaviour. Not always, but sometimes... mostly when i have a bad lift off.

[Ryan Legend]

Yep same here, first I thought it was turbulence. :P

[Cobra847]

If you suffer from this issue -- please try the following:

 

Set your cockpit shake level to 0% save and exit your settings.

Go back into your settings and set it to the desired level.

 

Hopefully that should 'reset' the cockpit shake levels. This bug is likely caused by a corrupted settings .db after the latest update.

[Art-J]

Just tested this method (including exiting the game and loading it up again) on take-off instant mission, but it doesn't work, at least not on my PC. Default 100% is the value I'm aiming at.

 

What is the 0% setting supposed to do anyway? Tested this one as well for the first time (same mission) - the "extra" shaking is gone, but there's still "intended" shaking during take-offs, manoeuvres and stalls (albeit maybe a bit smaller one :D).

[Wizard_03]

I tried the suggestion too, and I still have the same issue. I also tried a fresh download to no avail.

 

Just to let you know Cobra.

[bernp]

I'm having this issue also. I hope we can fix it soon. Love this jet. Thanks for your support.

Hi,

 

This bug has resurfaced for me since the last update. My setting for cockpit shake is the default setting (100).

 

For me it is happening every second flight, and only on the MiG-21bis.

 

i.e. on the first flight since I start DCS World, if I take a MiG-21bis the shaking level will be normal (only in hard maneuvers, stall, high alpha, etc). Normal 1G flight will be without shaking.

 

On the second flight the cockpit keeps shaking, even in "heart of the envelope" level flight of 1G, stable with no acceleration.

 

Whole cockpit shaking when airborne, no matter if its an air spawn or cold start.

 

Thanks in advance for taking a look at this!

 

S!
